Tire Safety Detecting System Based on ZigBee

This paper gives tire pressure real time monitoring system based on ZigBee. The pressure sensor and RF(Ray Frequency) emitter are installed in automobile tire. The collected data are transmitted to the receiver installed in an automobile by wireless communication channels. Fast CRC algorithm with half bit saves storage units and reduces RF communication error rate greatly, this paper analyzes and designs the wireless communication, studies and realizes the reliable transmission of the tire pressure and temperature between a transmitting module and a receiving module. The system can measure the tire real-time temperature and pressure, indicate the tire states and alarm at the dangerous states.
